AWS IoT FleetWise will no longer be open to new customers as of April 30, 2026. Existing AWS IoT FleetWise customers can continue using the service. The [Guidance for Connected Mobility on AWS](https://aws.amazon.com/solutions/guidance/connected-mobility-on-aws/) provides guidance on how to develop and deploy modular services for connected mobility solutions that can be used to achieve equivalent capabilities as AWS IoT FleetWise. # Monitor AWS IoT FleetWise with Amazon CloudWatch **Important** Access to certain AWS IoT FleetWise features is currently gated. For more information, see [AWS Region and feature availability in AWS IoT FleetWise](fleetwise-regions.md). Amazon CloudWatch metrics are a way to monitor your AWS resources and how they're performing. AWS IoT FleetWise sends metrics to CloudWatch. You can use the AWS Management Console, the AWS CLI, or an API to list the metrics that AWS IoT FleetWise sends to CloudWatch. For more information, see the [Amazon CloudWatch User Guide](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/). **Important** You must configure settings so that AWS IoT FleetWise can send metrics to CloudWatch. For more information, see [Configure your AWS IoT FleetWise settings](configure-settings.md).
